Description

Technical Field

[0001] This utility model relates to the field of urban rail transit technology, specifically to an auxiliary support device for a rail transit wheelset gearbox. Background Technology

[0002] When urban rail transit maintenance personnel carry out maintenance work on wheelset components, after the train wheelset is separated from the bogie, auxiliary support devices need to be installed at the gearbox hanger mounting position to allow the train wheelset to move smoothly between various maintenance stations. During the process, the gearbox drive end must be kept at a certain height and not touch the ground to ensure the safety of personnel and equipment. Because the gearbox is generally an eccentric structure, one end of the input shaft needs to be supported to prevent it from swaying downwards. When turning the wheels of the entire train, the gearbox is connected to the bogie using a gearbox hanger. When a single wheelset moves, an auxiliary support device is needed to support the gearbox and prevent the gearbox drive end from swaying downwards and damaging components and equipment.

[0003] However, in the existing technology, the roller is located directly below the gearbox. When using a non-drop wheel lathe to work on a single wheelset, the gearbox is unsupported and may swing down into the moving area of ​​the machine tool components, causing the machine tool to malfunction. Therefore, non-drop wheel lathes cannot be used for wheel turning, which reduces the utilization rate of the equipment.

[0004] In view of this, the present invention proposes an auxiliary support device for a rail transit wheelset gearbox. Utility Model Content
